DESCRIPTION

Compacted liquid detergent composition for laundry washing Field of the invention

The present invention belongs to the field of liquid laundry detergent compositions and their methods of use.

Background of the invention

There is a tendency in the industry towards the use of so-called compacted liquids that minimize the levels of water used. Such liquid laundry detergent compositions require the presence of anionic surfactant such as linear alkylbenzenesulfonate to provide tissue cleaning advantages as well as a suds suppressor to control the soaps generated during the washing process due to the presence of the anionic surfactant.

However, said compacted composition can often have high viscosities due to the relatively high concentration of cleaning materials such as anionic surfactants. Traditionally, hydroxyl-containing amines have been used in such compositions to ensure that the viscosity of the liquid laundry detergent composition is acceptable to the consumer. In addition, an acceptable viscosity is necessary to allow the processability of the composition during the manufacturing process. Hydroxyl-containing amines are often used as neutralizing agents for anionic detergent surfactants such as linear alkylbenzenesulfonate.

However, it is now desired to reduce the total level of said hydroxyl-containing amines.

The reduction of the level of hydroxyl-containing amines of laundry detergent compositions of known low relative humidity can result in a high viscosity of the composition that has a negative effect on the ability of the consumer to pour and dose the composition accurately. Also, the processability of the composition is affected since it is difficult to handle such viscous compositions during manufacturing.

US2006003913 and US6136769 describe a liquid laundry detergent composition, although they do not comprise 0.5% to 15% by weight of water.

US2014201927 and US2014338134 describe liquid laundry detergent compositions but these do not comprise from 10% to 30% by weight of a linear neutralized alkylbenzenesulfonate without amine. In addition, US2014338134 does not describe compositions comprising from 0.5% to 15% by weight of water.

US2010040884 describes a liquid laundry detergent composition but said composition does not comprise from 0.5% to 15% by weight of water or from 0% to 5% by weight of fatty acid.

Therefore, there is a need in the art for compacted liquid laundry detergent compositions containing low levels of hydroxyl-containing amine compounds, but having consumer acceptable and / or process acceptable viscosities.

It has been surprisingly discovered that the above problems are overcome with the specific formulation space of the present invention. The formulation space described below can provide a liquid composition that has a low relative humidity and that comprises low levels of hydroxyl-containing amine compounds but has an acceptable viscosity.

Summary of the invention

The present invention is a liquid laundry detergent composition comprising:

- from 10% to 30% by weight of the composition of a non-amine type neutralized linear alkylbenzenesulfonate;

- from 0% to 5% by weight of the composition of a non-ionic surfactant.

- from 0% to 5% by weight of the composition of a fatty acid;

- from 5% to 40% by weight of the composition of an alcohol selected from the group comprising ethylene glycol, 1,3-

Propanediol, 1,2-propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butanediol, 1,3-butanediol, diethylene glycol, triethylene glycol, polyethylene glycol, formal glycerol, dipropylene glycol, polypropylene glycol, diphenyl glycol, ether mixtures thereof, preferably the solvent is selected from the group comprising 1,2-propanediol, dipropylene glycol, polypropylene glycol, 2,3-butanediol, n-butyl ether of dipropylene glycol and mixtures thereof;

- less than 5% by weight of the composition of an amine containing hydroxyl;

Detailed description of the invention

Liquid laundry detergent

The liquid laundry detergent composition of the present invention is liquid in nature. That is, even if it comprises a solid dispersed in a liquid phase, the composition has the nature of a liquid and not of a solid or granulated composition. With respect to the laundry detergent composition of the present invention, the term "liquid" includes forms such as dispersions, gels and pastes. The liquid composition may also include gases in suitably subdivided form. However, the liquid composition excludes forms that are generally non-liquid, such as pills or granules.

Preferably, the liquid laundry detergent composition has a viscosity of between 300 mPa.s and 700 mPa.s, more preferably, between 350 mPa.s and 600 mPa.s at a shear rate of 1000 s-1. An illustrative method for measuring viscosity is to use a DHR1 rheometer from TA instruments using a distance of 1000 pm at 20 ° C according to the manufacturer's instructions.

The term "liquid laundry detergent composition" refers to any laundry detergent composition comprising a liquid capable of moistening and treating fabrics, e.g. Eg cleaning clothes in a household washing machine.

The liquid composition can be formulated as a unit dose article. The unit dose article of the present invention comprises a water soluble film that completely contains the liquid composition in at least one compartment. Suitable unit dose articles are described in more detail below.

The liquid laundry detergent composition can be used as a fully formulated consumer product, or it can be added to one or more additional ingredients to form a fully formulated consumer product. The liquid laundry detergent composition may be a "pretreatment" composition that is added to a fabric, preferably a stain of a fabric, before adding the fabric to a washing solution.

The liquid laundry detergent composition comprises a siloxane-based polymeric soap suppressant. The following describes in more detail suppressors of suitable siloxane-based polymer soaps.

The liquid laundry detergent composition comprises from 10% to 30% by weight of the linear alkylbenzenesulfonate composition.

Preferably, the liquid laundry detergent composition comprises less than 10% by weight, or even less than 5% by weight, or even less than 2% by weight of the liquid laundry detergent composition of an anionic surfactant neutralized with amine.

The liquid laundry detergent composition comprises between 0.5% and 15% by weight of the water composition and may have a relative equilibrium humidity of less than 65% at 20 ° C.

The composition comprises less than 5% by weight of the composition of a hydroxyl-containing amine compound. Suitable amines are described in more detail below.

The liquid laundry detergent composition comprises from 0% to 5% by weight of the composition of a non-ionic surfactant.

The liquid laundry detergent composition may comprise a structuring agent. Suitable structuring agents are described in more detail below.

The liquid laundry detergent composition of the present invention may comprise adjuvant ingredients.

The liquid laundry detergent composition comprises between 0% and 5% by weight of the fatty acid composition. Without intending to impose any theory, traditionally neutralized fatty acid with hydroxyl-containing amines has been used to act as a suppressant of soaps in said compacted liquids. However, in the absence of amines containing hydroxyl, such fatty acids would need to be neutralized with alkaline earth metals, such as sodium, potassium or magnesium. The problem is that such sodium, magnesium or potassium fatty acids crystallize and leave the solution in compacted compositions affecting the stability of the composition (i.e., it has a tendency to phase separation where at least two differentiated fractions are visible) and increasing the viscosity. Therefore, it is another advantage of the present invention to provide a compacted composition in which the soaps are regulated without the need for fatty acid.

number of hydrogen atoms with silicon bond with the appropriate amount of molecules X "- Ph, where X" is as described for X, but has aliphatic unsaturation in the terminal group, allowing the addition reaction with the atoms of hydrogen with silicon bond of the siloxane polymer.

The organopolysiloxane type material (A) may be a substantially linear polydiorganosiloxane or may have some branching. The branching may be in the siloxane chain, provided, e.g. for example, by the presence of some trifunctional siloxane units of formula ZSiO3 / 2, where Z represents a hydrocarbon, hydroxyl or hydrocarbonoxy group. Alternatively, the branching may be due to an organic or multivalent organosilicon moiety, e.g. eg, divalent or trivalent that binds siloxane polymer chains.

Examples of organic bonding (branching) units are C2-6 alkylene groups, e.g. eg, dimethylene or hexylene, or aralkylene of formula -X'-Ar-X '-, where Ar represents phenylene. Hexylene units can be introduced by the reaction of 1,5-hexadiene with Si-H groups and units -X'-Ar-X '- by the reaction of divinylbenzene or diisopropylbenzene. Examples of organosilicon type binding units are those of the formula - (CH2) d - (Si (CH3) 2 --O) e - Si (CH3) 2 - (CH2) d - where d has a value from 2 to 6 and has a value from 1 to 10; for example, binding units of the above formula can be introduced with d = 2 and e = 1 by reaction of divinyltetramethyldisiloxane with Si-H groups.

After the hydrosilylation reaction with the aromatic compound X "- Ph and the reactions that may be necessary with a branching agent, the residual Si-H groups of the organopolysiloxane can be reacted with an alkene, such as ethylene, propylene, isobutylene or 1-hexene, preferably in the presence of a hydrosilylation catalyst, to introduce the Y 'groups.

It is preferable that the number of siloxane units (DP or degree of polymerization) in the average molecule of material (A) is at least 5, more preferably 10 to 5,000. Especially preferred are materials (A) with a DP of 20 to 1000, more preferably 20 to 200. The final groups of the organopolysiloxane (A) can be any of those usually present in the siloxanes, for example, trimethylsilyl end groups.

The resin preferably consists of monovalent trihydrocarbonsiloxy groups (M) of formula R'3 SiO72 and tetrafunctional groups (Q) SO4 / 2 where R "represents a monovalent hydrocarbon group. The numerical ratio of M groups to Q groups is preferably in the range of 0.4: 1 to 2.5: 1 (equivalent to a value of a in the formula R'a SiO4-a / 2 from 0.86 to 2.15) and, more preferably, from 0.4: 1 to 1.1: 1 and, most preferably, from 0.5: 1 to 0.8: 1 (equivalent to a = 1.0-1.33) for use in laundry detergent applications. Organosilicon resin (B) is preferably a solid at room temperature, but MQ resins having an M / Q ratio greater than 1.2 can be used, which are generally liquid, although it is most preferred that the resin (B) be formed only by groups M and Q as defined above, can alternatively be used R groups "SiO3 / 2 (T) and groups Q. The organosilicon resin (B) can also c containing divalent units R "2 SD2 / 2, preferably without being present no more than 20% of all siloxane units. The R group "is preferably an alkyl group having 1 to 6 carbon atoms, most preferably methyl or ethyl, or phenyl. It is especially preferred that at least 80% and, most preferably, substantially all of the R" groups present Be methyl groups. Other hydrocarbon groups may also be present, e.g. eg, alkenyl groups, for example as dimethylvinylsilyl units, preferably in small amounts, most preferably not more than 5% of all R groups. "Hydroxyl groups bonded to silicon and / or alkoxy groups may also be present, eg ., methoxy.

Such organosilicon resins are well known. They can be prepared in solvent or in situ, e.g. eg, by hydrolysis of certain silane type materials. Hydrolysis and condensation are especially preferable in the presence of a solvent, e.g. eg, xylene, of a precursor of the tetravalent siloxy unit (e.g., tetra-orthosilicate, tetraethyl orthosilicate, polyethyl silicate or sodium silicate) and a precursor of monovalent trialkylsilyloxy units (e.g., trimethylchlorosilane, trimethyloxysilane , hexamethyldisiloxane or hexamethyldisilazane). The resulting MQ resin can also, if desired, be trimethylsilylated to remove residual Si-OH groups by reaction or heat the presence of a base to give rise to the self-condensation of the resin by removing Si-OH groups.

The organosilicon resin (B) is preferably present in the antifoam at 1-50% by weight with respect to the organopolysiloxane (A), especially at 2-30% and, most preferably, at 4-15%.

The organosilicon resin (B) may be soluble or insoluble (not completely dissolved) in the organopolysiloxane (A) when present in the above amounts. The solubility can be measured by observing a mixture of (A) and (B) in

an optical microscope Improved foam control has been achieved in detergent applications both by compositions containing dissolved organosilicon resin (B) and by compositions containing dispersed particles of organosilicon resin (B). Factors that affect the solubility of (B) in (A) include the proportion of X-Ph groups in (A) (more X-Ph groups increase solubility), the degree of branching in (A), the nature of the groups Y and Y 'in (A) (long chain alkyl groups decrease the solubility), the ratio of units M to Q in the resin MQ (B) (a greater ratio of groups M to groups Q increases the solubility) and the molecular weight of (B). The solubility of (B) in (A) at room temperature can therefore be 0.01% by weight or less to 15% or more. It may be advantageous to use a mixture of a soluble resin (B) and an insoluble resin (B), for example, a mixture of MQ resins having different M / Q ratios. If the organosilicon resin (B) is insoluble in organopolysiloxane (A), the average particle size of the resin (B), measured when dispersed in liquid (A), can be, for example, from 0.5 to 400 pm, preferably from 2 to 50 pm. For industrial foam control applications such as defoaming black liquor in the paper and pulp industry, resins that are soluble in the siloxane copolymer, such as MQ resins having an M ratio are usually preferred / Q.

The resin (B) can be added to the antifoam as a solution in a non-volatile solvent, for example an alcohol such as dodecanol or 2-butyloctanol or an ester such as octyl stearate. The resin solution prepared in a volatile solvent, for example, xylene, can be joined with the non-volatile solvent and the volatile solvent can be removed by purification or by other forms of separation. In most cases the nonvolatile solvent can be left in the antifoam. It is preferred to dissolve the resin (B) in an amount of nonvolatile solvent equal to or less, more preferably not more than about half of its weight in solvent. The resin (B) may alternatively be added in solution in a volatile solvent after solvent purification. If the resin (B) is added as a solution and is insoluble in organopolysiloxane type material (A), when mixed it will form solid particles with an acceptable particle size.

The resin (B) may alternatively be added to the antifoam in the form of solid particles, for example spray-dried particles. MQ spray-dried resins are marketed, for example, with an average particle size of 10 to 200 micrometers.

The level of insolubility of the resin (B) in organopolysiloxane type material (A) can affect its particle size in the composition. The lower the solubility of organosilicon resins in organopolysiloxane type material (A), the larger the particle size tends to be when the resin is mixed as a solution in (A). Therefore, an organosilicon resin soluble at 1% by weight in organopolysiloxane type material (A) will tend to form particles of smaller size than a resin that is only soluble at 0.01% by weight. Organosilicon resins (B) that are partially soluble in organopolysiloxane type material (A), that is, have a solubility of at least 0.1% by weight, are preferred.

The molecular weight of the resin (B) can be increased by condensation, for example, by heating in the presence of a base. The base may be, for example, an aqueous or alcoholic solution of potassium hydroxide or sodium hydroxide, e.g. eg, a solution in methanol or in propanol. We have found that for some detergents, the most effective in reducing foam are antifoams that contain the lowest molecular weight MQ resins but those that contain high molecular weight MQ resins more reliably provide the same reduced foam levels in different conditions, for example at different washing temperatures or in different clothes washers. The high molecular weight MQ resins also have a better resistance to loss of efficiency over time when stored in contact with the detergent, for example as an emulsion in liquid detergent. The reaction between resin and base can be carried out in the presence of silica, in which case there could be some reaction between the resin and the silica. The base reaction can be carried out in the presence of the organopolysiloxane (A) and / or in the presence of the nonvolatile solvent and / or in the presence of a volatile solvent. The base reaction can hydrolyze a non-volatile ester solvent such as octyl stearate, but we have found that this does not detract from the effectiveness in terms of foam control.

The third essential ingredient is a hydrophobic filler (C). Hydrophobic fillers for defoamers are well known and can be materials such as silica, preferably with a specific surface area measured by BET measurement of at least 50 m2 / g, titania, crushed quartz, alumina, aluminosilicates, organic waxes, e.g. eg, polyethylene waxes and microcrystalline waxes, zinc oxide, magnesium oxide, salts of aliphatic carboxylic acids, reaction products of isocyanates with certain materials, e.g. eg, cyclohexylamine, or alkylamides, e.g. eg, ethylenebisestearamide or methylenebisestearamide. Mixtures of one or more of these are also acceptable.

Some of the aforementioned fillers are not hydrophobic in nature, but can be used if hydrophobic are made, which can be carried out either in situ (i.e. when dispersed in the organopolysiloxane type material (A)), or by pretreatment of the load before mixing it with the material (A). A preferred filler is silica that becomes hydrophobic, which can be carried out, e.g. eg, by treatment with a fatty acid, but is preferably performed by the use of methyl substituted organosilic materials. Suitable hydrophobicizing agents include polydimethylsiloxanes, dimethylsiloxane polymers having silanol block end groups or silicon bond alkoxy groups, hexamethyldisilazane, hexamethyldisiloxane and organosilicon resins comprising monovalent groups (CH3) 3 SiÜ1 / 2 and tetravalent groups SiÜ2 in a ratio of 0.5 / 1 to 1.1 / 1 (MQ resins).

It is usually carried out at a temperature of at least 80 ‘C. Similar MQ resins can be used as organosilicon resin (B) and as a hydrophobicizing agent for silica loading (C).

Preferred silica materials are those prepared by heating, e.g. eg, fumed silica, or by precipitation, although other types of silica such as those obtained by gel formation are also acceptable. The silica filler may, for example, have an average particle size of 0.5 to 50 micrometers, preferably 2 to 30 pm, most preferably 5 to 25 pm. Such materials are well known and are commercialized, both in hydrophilic form and in hydrophobic form.

The amount of filler (C) in the antifoam is preferably 0.5% to 50% by weight with respect to the organopolysiloxane type material (A), especially 1 to 10% or 15% and, most preferably, of 28%. It is also preferred that the ratio of the resin weight (B) to the load weight (C) is 1/10 to 20/1, preferably 1/5 to 10/1, most preferably 1/2 to 6 / one.
